- You may be looking for the Dark Time.
The Dark Times was one of the earliest aeons in the history of the universe.
Occurring after Gallifrey was born, (COMIC: Agent Provocateur) the Tenth Doctor described this as a time of chaos "before our reality" when the Nestenes and Great Vampires flourished, (TV: The Infinite Quest) as well as the Carrionites. (TV: The Shakespeare Code) The Carrionites waged a war with the Hervoken. (PROSE: Forever Autumn) The Eternals were present during this time period, banishing both the Carrionites and the Hervoken to the Deep Darkness but some of them escaped. (TV: The Shakespeare Code, PROSE: Forever Autumn) The Racnoss were alive during this time period, with the last-named species having its defeat at the hands of the Fledgling Empires. (TV: The Runaway Bride) The Mandragora Helix also originated during this era. (PROSE: Beautiful Chaos) The Great Old Ones were also present in the universe at this time. It was during this time period, too, that the legendary spaceship Infinite was created. (TV: The Infinite Quest) The Kamishi, also known as the First Race, one of the earliest known civilisations, lived in this time period as well. (AUDIO: The Rulers of the Universe)
The Time Lords fought the Great Vampires during this time and, led by Rassilon, they made Bowships to kill the beasts. They killed all but one after a war so long and bloody that the Time Lords were sickened of violence and officially began their long period of non-interference. (TV: State of Decay)
